TDK Announces 100GB Blue Laser Disc Technology 6 June 2005

TDK has developed a prototype recordable Blu-ray high recording densities, such as those employed Disc with revolutionary 100GB capacity. By far the by the Blu-ray Disc format. The formulation’s most advanced optical media ever developed, the optical qualities are so stable that TDK has already prototype 100GB bare Blu-ray Disc doubles both been able to achieve 6x (216Mbps) recording the capacity and recording speed of the current Blu- speed in the lab with blue laser media. ray Disc specification. Blu-ray’s industry-leading capacity means a single disc can store a vast Because Blu-ray Disc media’s data tracks are assortment of content without making quality quite narrow even in comparison with DVD media, compromises. A single, prototype 100GB Blu-ray precise, stable interaction between the laser and Disc can store approximately 9 hours of high the recording material is especially critical to definition video. ensuring error-free recording and playback. That’s why TDK developed DURABIS, an Recently unveiled in Tokyo, Japan, TDK’s new innovative hard coating technology that makes bare prototype Blu-ray Disc records data at 72 megabits Blu-ray Disc media a reality by protecting the disc per second, double the 36Mbps rate of the current surface against common contaminants such as Blu-ray Disc specification. The increased speed scratches, fingerprints and dust adherence. has been accomplished through recent advancements in disc recording layer formulations. DURABIS increases the scratch resistance of Blu- The initial Blu-ray Disc standard allows for 25GB ray Disc media by a factor of 100, as demonstrated single layer Blu-ray Discs and 50GB dual layer Blu- in rigorous testing. Because the DURABIS coating ray Discs. To achieve 100GB capacity, the technology rapidly discharges static electricity, the prototype Blu-ray Disc incorporates four 25GB discs also resist the accumulation of dust. layers. Like all Blu-ray Disc media, TDK’s prototype 100GB Blu-ray Disc is single sided. TDK’s creation of DURABIS has eliminated the need for cumbersome cartridges to protect the Hideki Hirata, TDK Engineering Manager, noted, media’s recording layer and is allowing the “Anticipation surrounding the release of the baredevelopment of bare Blu-ray Disc media. Blu-ray Disc format continues to grow. Although Eliminating the need for a cartridge will minimize there’s been considerable speculation regardingmanufacturing costs. What’s more, with next-generation Blu-ray Disc capacities, TDK is the DURABIS coating technology allowing the first to successfully achieve 100GB in a working, production of bare Blu-ray Discs, the format will prototype disc. TDK’s development of a allow for the same user experience as with prototype 100GB Blu-ray Disc with double the today’s CDs and DVDs. recording speed of the current specification validates the company’s position as a leader in As a member of the Blu-ray Disc Association Board extending the capabilities of optical media.� of Directors, TDK has played a key role in the development of Blu-ray, the next generation optical TDK technologies are redefining state-of-the-art media format that will not only change the way we optical media specifications and performance. The experience home entertainment and computing, but company’s advanced sputtering technology will also create unprecedented business played a key role in enabling the creation of the efficiencies. prototype100GB Blu-ray Disc. Additionally, TDK’s new inorganic film formulation provides absolute stability with narrow track pitches and
